Title: Magnetic disk
Inventor: SHIBATA MAKOTO
IPC: G11B5/84
Filed: 1990-11-17
Abstract: PURPOSE:To reduce the production cost of driving by creating servo information onto the disk at the point of the time when the magnetic disk is produced. CONSTITUTION:A resin molded by injection molding is formed as a substrate 11 and pits 12 are provided at the time of the injection molding on the surface on the side of the substrate 11 to be imparted with a magnetic thin film. Namely, the disk substrate 11 is made of the resin. Further, the information on the position used for reference at the time of applying servo is created in the form of the pits 12. The presence of the pits 12 are read out as reproduced electric signals from an ordinary head after the disk is built into a drive. The deviation from the desired track position is thus known, by which the servo is applied. The time for assembling the drive and the cost associated with the assembly are saved in this way.

Title: Grinding device
Inventor: SHIRAKI YASUHIRO
IPC: B24B37/02
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To machine an object in the almost complete round shape in a short time by forming a groove in which grinding material for grinding the member to be ground is adhered in the surface facing the member to be ground in a disk. SOLUTION: When a rotational shaft 8 connected with a driving source is rotated clockwise for example, a lower side disk 4 rotates clockwise, and a ceramic member 2 accommodated in an opening 5 of a holding disk 6 rotates in the opening 5 following the disk 4's rotation. Following the ceramic member 2'S rotation, an upper side disk 3 unconnected with the rotational shaft 8 rotates counterclockwise oppositely to the rotational direction of the disk 4.

Title: Compressor controller for cooler for vehicle
Inventor: OOKUMO HIROYA
IPC: B60H1/32
Filed: 1986-12-26
Abstract: PURPOSE:To improve the traveling performance on start acceleration and improve the cooling faculty in the intermediate or high speed region by setting the region on the stop of a compressor after the high load state of an engine is detected according to the map of the engine load and the car speed. CONSTITUTION:The detection signals supplied from a sensor 3 for detecting the pressure in a suction pipe 1 and a car speed sensor 4 are input into a compressor control device 5. A compressor 7 is operated through a relay 6 and an electromagnetic clutch 8 by the control signals supplied from the controller 5. In this case, if the intake pipe pressure is equal in the relation between the car speed and the intake pipe pressure (engine load), the load is set to the stop region of the compressor 7 as the car speed is lower. Therefore, on start acceleration, the traveling performance is improved by spreading the engine load region for stopping the compressor 7, and the cooling faculty is improved by contracting the engine load region in the intermediate or high speed region.

IPC: G03G15/08
Filed: 1991-10-31
Abstract: PURPOSE:To achieve the accurate quantitative-control of the concentration of the toner in developer and to make a device compact by means of the simple constitution. CONSTITUTION:A replenishment toner storage hopper 20 is provided on the top of a developer container 18, storing developer 24, via a mesh 19 through which toner particles can pass. A magnet roller 17 in which NS-pair magnetic poles are uniformly arranged around the periphery so that they are alternately arrayed the circumferential direction is arranged close to the mesh 19 below the replenishment toner storage hopper 20 in the developer container 18 so that it can be rotated and driven. Thus, toner (a) in the replenishment toner storage hopper 20 is scraped towards the developer container 18 by the use of a magnetic brush formed on the periphery of the magnet roller 17. Also, magnets 25a-25d or magnetic bodies are arranged in the vicinity of the developer container 18. By the change in a magnetic field produced in the area between the magnet roller 17 and them, the flowability and stirring performance of the developer 24 are improved, thereby speeding up the rise of the amount of the electrification and preventing the solidification of the developer 24.

Title: Air-tight seal method in very low temperature tank
Inventor: KAMIOKA YASUHARU
IPC: F16J13/02
Filed: 1990-11-19
Abstract: PURPOSE:To perform an air-tight seal at a low cost and easily by setting roughness of an obverse of a flange part and a surface of a cover unit to a specific value, and applying silicon grease or an epoxy adhesive agent annularly to the total periphery in the peripheral direction so that a width in a radial direction of the flange part obtains specific dimension. CONSTITUTION:An obverse 2A of a flange part 2 of a tank main unit 1 and a lower surface 4A of a cover unit 4 are left as finished so that roughness of the surfaces obtains 6.3mum or less maximum roughness Rmax. Silicon grease or an epoxy adhesive agent 10 is left as applied annularly over the total circumference of the flange part 2 in a 5mm or more width on the obverse 2A of the flange part 2. Thereafter, the cover unit 4 is placed on the tank main unit 1 and tightened by bolts by bringing the lower surface 4A of the cover unit 4 into contact with the obverse 2A of the flange part 2. Sufficient air-tight seal performance can be thus obtained by using not a particular and expensive low temperature seal member but only the cheap silicon grease or epoxy adhesive agent, and a cost for an air-tight seal can be decreased to perform work very simply and easily.

Title: Semiconductor device
Inventor: KIMURA TAKEMI
IPC: H01L21/31
Filed: 1987-12-10
Abstract: PURPOSE:To improve moisture resistance by preventing the containing of phosphorus as an active ingredient in an insulating film being in contact with an aluminum electrode in a bonding pad section. CONSTITUTION:A silicon oxide film 4 and a phosphate glass film 5 as inter-layer insulating films are formed onto a polycrystalline silicon wiring 3, and the phosphate glass film 5 is removed selectively to shape an opening 8. A contact hole is bored to the silicon oxide film 4 and an aluminum electrode 6 is shaped, and a silicon nitride film 7 is formed as a passivation film. Consequently, the aluminum electrode 6 in a bonding pad section is formed in structure in which it is not brought into contact directly with the insulating films containing phosphorus, and moisture does not react with phosphorus near the aluminum electrode 6 in the bonding pad section even when moisture intrudes from the outside. Accordingly, the aluminum electrode 6 in the bonding pad section is not corroded, thus improving moisture resistance.

Title: Method and arrangement for adaptive echo compensation
Inventor: MATT HANS JUERGEN
IPC: H04M9/08
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To compensate an echo which causes unnecessary coupling between signals in the receiving direction and those in the transmitting direction in a transmission system by using a digital filter. SOLUTION: An appropriate arrangement contains a first digital filter 1 which continuously calculates filter factors in accordance with an NLMS (normalized least mean square) algorithm. The filter factors are stored after the factors are weighted and the optimum value is used for the adjustment of a second digital filter 7. The output signal 9 of the filter 7 is subtracted from signals affected by echoes, resulting in echo-free output signals (10). Therefore, natural sound transmission can be performed even when disturbance occurs for a short time.
